Cagrilintide is a long-acting analogue of amylin, a naturally occurring peptide hormone that is co-secreted with insulin by pancreatic β-cells following food intake.

Unlike Semaglutide, Tirzepatide and Retatrutide, which act primarily through incretin pathways, Cagrilintide targets amylin and calcitonin receptor systems, introducing a complementary mechanism for regulating appetite and energy balance. This distinct pharmacology has made it one of the most important investigational compounds in modern metabolic peptide research.

Because its mechanism differs fundamentally from GLP-1 receptor agonists, Cagrilintide has become an important molecule for researchers investigating combination therapies that engage multiple appetite-regulating pathways simultaneously.

Why Cagrilintide matters in metabolic research

Cagrilintide represents one of the first long-acting amylin analogues capable of maintaining sustained receptor activation through once-weekly administration in published clinical research.

Its unique mechanism has made it an important research tool for studying:

appetite regulation
satiety signalling
gastric emptying
energy balance
body-weight regulation
amylin biology
combination therapy with GLP-1 receptor agonists

Rather than replacing GLP-1 agonists, Cagrilintide is frequently investigated as a complementary metabolic peptide because it activates physiological pathways that differ from incretin signalling alone.

How Cagrilintide works

Cagrilintide primarily activates amylin receptors, with additional activity through calcitonin receptor complexes.

Amylin is released naturally alongside insulin after meals and contributes to physiological regulation of:

satiety
gastric emptying
glucagon secretion
food intake

Unlike GLP-1 receptor agonists, which primarily amplify incretin signalling, Cagrilintide reproduces key aspects of endogenous amylin physiology. This complementary mechanism explains why it has become a major focus of combination research with Semaglutide and other incretin-based peptides.

Published clinical findings on Cagrilintide

Human clinical studies have demonstrated that investigational Cagrilintide produces dose-dependent reductions in body weight together with improvements in appetite control and satiety. In the Phase 2 dose-finding trial published in The Lancet, once-weekly Cagrilintide produced significantly greater body-weight reduction than placebo and was generally well tolerated across the investigated dose range.

One of the most important developments in subsequent research has been the investigation of Cagrilintide in combination with Semaglutide. Rather than acting on the same receptor, the two molecules engage complementary biological pathways, allowing researchers to evaluate whether combined amylin and GLP-1 signalling produces broader metabolic effects than either mechanism alone. Later combination studies supported this rationale and helped establish Cagrilintide as a leading partner for GLP-1-based metabolic research.

Published safety and tolerability findings

Published clinical studies indicate that the most frequently reported adverse events with investigational Cagrilintide are gastrointestinal, including nausea, vomiting and gastrointestinal discomfort. Similar to GLP-1 receptor agonists, these events were generally dose-related and occurred most often during dose escalation. Most were reported as mild to moderate in severity.

Because Cagrilintide is commonly investigated alongside GLP-1 receptor agonists, tolerability remains an important component of ongoing clinical research. Published studies therefore evaluate not only efficacy, but also the balance between appetite-related outcomes and gastrointestinal tolerability.

Published dosing schedules used in Cagrilintide research

Published clinical studies generally investigated once-weekly administration with gradual dose escalation rather than immediate initiation at higher maintenance doses. Phase 2 obesity studies evaluated several dose levels to characterise both efficacy and tolerability across the dose range.

More recent combination studies evaluating Cagrilintide together with Semaglutide have continued to use structured escalation schedules similar to those employed throughout the broader incretin field. These published schedules are presented as summaries of clinical trial design and should not be interpreted as instructions for use.

Storage: unopened lyophilized vials are best stored refrigerated at 2–8°C, which is the storage method confirmed by our manufacturing partner and suitable for up to 24 months. Refrigeration is preferred because it minimizes unnecessary freeze–thaw cycles during routine handling. If substantially longer-term storage is required, unopened lyophilized vials may also be kept frozen. Once reconstituted, always store at 2–8°C and do not freeze.

Reconstitution and handling

Cagrilintide is supplied as a lyophilised vial and should be handled using standard peptide reconstitution procedures appropriate to the research setting. Must be reconstituted with bacteriostatic water before use. GLP-1 class peptides are sometimes slow to dissolve and require very gentle reconstitution to avoid foaming or remaining slightly cloudy.

For other solvent selection, concentration planning and storage guidance, see the full Peptide Reconstitution Guide and Reconstitution Calculator.

FAQ

What is Cagrilintide?

Cagrilintide is a long-acting analogue of the hormone amylin, designed to reproduce and prolong physiological amylin signalling. Unlike GLP-1 receptor agonists, it primarily targets amylin receptor pathways, making it one of the leading investigational peptides for studying appetite regulation and satiety biology.

How does Cagrilintide work?

Cagrilintide activates amylin receptor systems involved in satiety, gastric emptying and energy balance. Its mechanism complements rather than duplicates GLP-1 receptor signalling, which is why it is frequently investigated alongside GLP-1 agonists such as Semaglutide.

Why is Cagrilintide often combined with Semaglutide?

Cagrilintide and Semaglutide act through different biological pathways. Cagrilintide primarily targets amylin receptor signalling, while Semaglutide activates the GLP-1 receptor. Published clinical research has investigated whether combining these complementary mechanisms can produce broader metabolic effects than either pathway alone.

How is Cagrilintide different from GLP-1 receptor agonists?

Unlike Semaglutide, Tirzepatide and Retatrutide, Cagrilintide is not an incretin receptor agonist. It is a long-acting amylin analogue with a distinct mechanism of action, making it an important addition to metabolic research rather than simply another GLP-1-derived peptide.

What research areas commonly investigate Cagrilintide?

Published studies have investigated Cagrilintide in relation to appetite regulation, satiety signalling, body-weight outcomes, gastric emptying, energy balance and combination therapy with GLP-1 receptor agonists. Its unique pharmacology has made it one of the leading molecules in amylin-based metabolic research.
